"Haderaue" is part of a nature reserve of 165 ha
in the "Inselrhein" section of the Rhine river between the cities
of Mainz and Bingen. The "Inselrhein"
[
map] is where the waters of the Rhine flow with a very
low pace and the river has a width of up to one km. This is due to
the afflux caused by the hard quartzite rocks at the “Binger Loch"
[at
N 49° 58' 33", E 7° 52' 22"] that narrow the river and
hinder the water’s free flow. The low flowing speed causes a
sedimentation of gravel and sands. Normally the river would form
meanders in this case. But as the area available to the river is
limited here by the hills of the "Rheinhessisches Tafel- und
Hügelland" to the left and by the Taunus mountains on its right,
instead islands emerged in the middle of the river: the
"Rheinauen".Also "Haderaue“ was one of these islands still two centuries ago, but it eventually lost its island character due to continuous aggradation.
To log your visit:
1. Find the ford crossing the “Krappen” in the southwest of Haderaue and take a picture there. The "Krappen" should be clearly visible. Optional: It would be cool to see you or your GPSr, your bicycle, mascot, etc. on the picture, too.
2. Send the answers to the following questions to g e o w a s (at) g m x . d e :
a) Explain in your own words what the “Krappen” is and why and how it was formed.
b) When at the latest was the “Krappen” completely detached from the river?
c) The outlines of “Haderaue” can still be identified if you carefully observe the landscape. What is the approximate length of this former island today? This question is somewhat more tricky. But on the other hand there are plenty of ways to find an adequate answer (±100 m will do). A map can be of help.
3. If your answers are ok, you will receive an e-mail with the permission to log. To your log attach the picture you took. But be careful not to include any answers to the questions above. Early logs (prior to permission) or logs that do not fulfill the requirements I will have to delete.
For cachers who don’t speak German at all and struggle with the questions: Take the picture and tell me as much as you can about the “Haderaue” floodplain.
If you like to spend some more time at "Haderaue" you are welcome to also find the bonus cache GC1RANP!
Happy caching!

Bei einsetzendem Hochwasser haben wir einen Spaziergang zwischen Budenheim und Heidenfahrt gemacht. Von der Haderaue sind derzeit (Pegel Mainz 5,70m) nur die Bäume zu sehen.
Danke fürs Zeigen und

Der Cache ist an einem schönen Ort und lohnt sich immer noch, der Versuch, die Loggbedingungen zu erfüllen, aber leider nicht. Der Owner hat bisher nicht auf meine Mail reagiert, weshalb ich jetzt hier loggen werde, da ich davon ausgehe, dass meine Antworten soweit richtig waren.

zusammen mit pilemoje bin ich heute von der Radfahrerfähre bei Budenheim zur Haderaue gelaufen. Was ein idylisches Gebiet. Den Weg am Rhein entlang mit Blick auf Walluf und Eltville haben wir sehr genossen.
Da dieser Earthcache in der Nähe war sind wir durch die Furt zu den Infotafeln gelaufen und konnten die Fragen gut beantworten.
vielen Dank für den interessanten Earthcache bzw den virtuellen Cache auf OC sagt Riedxela.
